Using a pantriagonal 4x4x4 magic cube and a pantriagonal 5x5x5 magic cube there are three possibilities to construct a pantriagonal 20x20x20 magic cube.
Take as first grid 125x pantriagonal 4x4x4 magic cube and as second grid 4x4x4 'blown up' pantriagonal 5x5x5 magic cube. See below the grids and result of level 1.
Take 1x number from first grid with 125x pantriagonal 4x4x4 magic cube [level 1]
